Full m/lab SD2000 schematics

G`day Geshi

Looking at photos the sd2100 is very similar to the 2000,just different logic cct and
no crystals plus other small changes.
The sd2200 gets the mcu,i have done a lot of modding on the 2200 and its this point that i start to see a real shift away from the type of circuitry that you see in the 2000 although
the transmit cct is pretty much the same.

King of the hill

G`day JC1,

Yeah it would be nice to boot m/lab of and be king of the hill,
I would like to have a peek inside m/labs latest offering but i dont
own one,i have a 3000 and have modded it some,its a very nice
detector to own but i dont think there detectors have advanced
much since the gp extreme,just bells and whistles and digital.

I think what makes m/lab tuff to beat is the way they do there
sampling also there willing to push there detectors a little further
hence the em interferance plus they design there detectors in
a country with some of the worst ground in the world.

Now when i say sampling im not talking about the sd2000 i
am referring to the gp series detectors,the gp detectors
timings are a lot more complicated as apposed
to the sd2000 especially with the dual voltage that they
use on there transmit,quite innovative i think.
Also i am a little suspicious of there sensitive smooth mode on
the 4000,
sounds like there re-inventing channel one.

Cheers Zed

You cant pop models like GPX just like that. Not to mention it's patented technology and will take tons of time to modify the technology so it will go around those patents. Very nice info, thanks for posting it. I suppose later models (SD2200) has pretty much the same circuit with added MCU.

Coffee

Hi Zed,

Coffee would be fine for me.

Sireously, if we could get the

4500 info, we could beat

minelab with the next new detector

and make lots of $$$$$$$$$$$$.

Cause everyone has to throw away

the old no good models and get the

new and slightly improved model.

And have it made in china..

out the door for $5,000.00

And would you like tea or coffee with that.

Zed

Actually

Actually instead of the 4k,

please get the circuitry

for the 4500.

Oh and the software,

disassembled and with

comments.

Please and Thank you.

If you don't know about

the 4500, wait a few months

it will be out.

Any chance of getting the 4k's circuitry?


galah.

Thank you for your kind remarks guys,
im glade that you enjoyed them,its nice
to give something back after many years
of cruising pi forums looking for pi info.

Thank you very much for the 2000 circuit , help to understand some electronic function .
Share that is a must ,thank you again

Hi ZED
Thanks for uploaded SD2000 circuit, your work was great for people like
Study and teaching more in the matter.
Best regards.
